Detailed Description

template<typename PointT>
class pcl::GridMinimum< PointT >

The GridMinimum class creates a 2D grid over the input point cloud data. Then, in each cell (i.e., 2D grid element), all the points present will be downsampled with the minimum z value. This grid minimum can be useful in a number of topographic processing tasks such as crudely estimating ground returns, especially under foliage.
